Brief summary

The purpose of this study is to determine if IN fentanyl (1.5 µg/kg) or IN ketamine (1 mg/kg) is more effective at 30 minutes than oral morphine (0.5 mg/kg) in reduction of moderate and severe pain associated with limb injuries in patients 2-17 years of age presenting to the ED.

Detailed description

In children with moderate to severe pain due to musculoskeletal injuries, the first-line analgesic therapy in pediatric emergency departments (ED) is oral or intravenous morphine. Due to the delay or discomfort associated with establishing IV access, oral forms are preferred in French ED. Unfortunately, oral morphine alone or with ibuprofen or paracetamol, none regimen is optimal for relieving pain in children with traumatic limb injuries. However, the use of intranasal course is a safe route that can provide rapid and almost immediate analgesia. Intranasal administration is easy, non-invasive and usually well tolerated by children. In the last years, drugs with analgesic and sedative properties is increasing, particularly on fentanyl, ketamine, which can be also administered by the IN route. There are currently no studies, neither published nor ongoing, which compare IN fentanyl or IN ketamine to a standard oral morphine for children with acute moderate to severe pain with limb injuries presenting to the ED. The main hypothesis is that the efficacy of the analgesia 30 minutes after the administration will be higher with IN Fentanyl or with IN Ketamine, when compared to oral morphine.
